Cobweb model with conformable fractional derivatives

Mathematical Methods in the Applied Sciences, 2018
In this paper, the cobweb model is reformulated in terms of fractional‐order derivatives. In particular, we describe linear cobweb models in continuous time by using conformable fractional‐order derivatives. Then, the general solutions as well as stability criteria for the proposed models are given.
